Abstract
According to integral characterization of gene frequencies of the investigated loci AB0, MN, Rh, GLO1, PGM1, EsD, AcP, 6-PGD, Hp, Tf, Gc, C'3 and ChE2, Mongolian population has high level of polymorphism, with the exception of haplotypes R"(cdE) and R(y)(CdE) at the Rh locus and Tf(B0-1) at the Tf locus. The data on biochemical and immunological polymorphic gene markers analysed in the population of Mongolia show that the Mongolians have some distinctive features, in comparison with the mean-in-the-world characteristics: high frequencies of the B genes at the AB0 locus; D, E, R1 and R2 at the Rh locus; GLO 1(1), PGD(c), Tf(D)Chi), E2(C5+), PGM1(1+); low frequencies of the genes A(AB0), R0(Rh), Acp(c), Hp1, Gc2, C'3F, PGM 1(2-); the rest of the genes at the above-mentioned loci and the genes of the locus MN have the mean-in-the-world frequencies.

Abstract
The hemp plant (Cannabis sativa L.) has a long tradition of being used for many different purposes such as industry, medicine and nutrition. In particular, because hemp seed (HS) is rich in oil protein and considerable amounts of dietary fiber, vitamins and minerals that are particularly suitable also for animal nutrition. Different studies have evaluated HS on qualitative and quantitative properties of livestock products but as of today, nobody has investigated the molecular pathway behind HS supplementation in farm animals. Thus, in this study, we will report the first RNA sequencing of the whole-blood transcriptome of ewes fed either with a controlled diet (CTR, n = 5) or with a diet supplemented with 5% of hemp seed (HSG, n = 5). Applying a false discovery rate (FDR) <0.05 and a log(2)FC either higher than 0.5 or lower than -0.5, we identified 314 differentially regulated genes in the HS-supplemented group compared to the CTR group. Several genes encoding for different subunits belonging to the complex I, II, III, IV and ATP-synthase were up-regulated making oxidative phosphorylation (FDR: 3.05e-19) and thermogenesis (FDR: 2.17e-16) the highest up-regulated pathways in our study. Moreover, we found up-regulation in different genes involved in lactose biosyntheses such as GALK1 and PGM1 and, as a result, we observed a statistically higher lactose percentage in the HSG group (p < 0.05). These results indicate that HS supplementation positively affects the energy production pathway in lactating ewes conferring them also more resistance to adverse climatic conditions such as low temperature. Finally, the higher milk lactose content makes the derived dairy products more profitable.
